To all wlz om'z't may concern I Be it known that 1, CHARLES a citizen of, the United States, residing at Dorchester, in the county of Suffolk and 5 Stateof Massachusetts, have invented an Improvement' in Warp-Leasing Machines,

. of which the following'description, in con-- 'nection with the accompanying drawings, is

representing like parts.-

My invention relates particularly towarp leasing machines intended for mechanically leasing a warp, and particularly a new warp, which it is desired to have leased prior to 15 its insertion in the loom.

My invention will be best understood reference to the following specificatiom when taken in'connection with the-accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims;

In the.drawings,-Figure 1 is an elevation, partly broken away, showing a machine embodying one form of my invention; Fig. 2 shows the same'machine in end elevation; Fig.3 is a fragmentary view, with various parts removed to show the relation of the needle to the lease rods and the warp when seizing a thread thereof; Fig. 4:" is a similar but more elaborated View showing the needle inits retracted position, Fig... 5 is a .view similar to Fig. 3 showing the advanced needle but the reversed or shifted vation on an enlarged scale of the warpfee-ding ratchet and pawl de'vice, and Fig.

' 7, is an end elevation of the same.

While the various elements of the machine to' be described may be arranged in a reciprocatbry warp drawing needle and operating mechanism therefor," which: car- I riage' is caused to advance progressively lengthwise thelmjachine'totraverse the-warp, the latter being. maintained with its. threads under tension and arranged in substantially-I parallel aline'ment," .The advancing needle is caused to seize the-foremost' warp thread and to draw the same betweensliitably positioned lease members,- there beingprovided to cooperate with the-needle suitable-strip- D.

t my. nvention a there is provideda bed or frame a, suitably supported by'the: legs 0;- and carrying the overhead structurecor arched frame a which 7 serves as a supportfor'the. warp carriage, lease members and other mechanism.

The warp is sustained du'ring the. operation of the'machine ina warp carriage or holder of any suitable construction but which here comprises the end frame memhers I), which are connected by apair' of 4 rods 6, and have each the'upper and lower clamping jaws b and b respectively. The carriage is supported uponthe' frame by--a pair of oppositely extended hanger rods 6*,

resting on roller supports 6 and thereby sustaining the carriage forlongitudinal adjustment lengthwise I the machine; The

frame members are also provided withoppo-r sitely extended lower supporting rods b which the weight of the carriage causes to pre's'sagainst vertically disposed rollers bf I on thestationary frame of themachine. 'The warp. when positioned in the machine, I

has its free ends clam ed by the usual clamp bar 0 (Figs. 3-5) which is placed in the upper pair of-cl'amping jaws 6?. When in that position the previously withdrawnseparator shaft d (Fig. 4) is replaced in the machine and the threads are clamped .byei'second clamp bar. 01 placed in the lower pair of.

clamping jaws P, so that the warp assumes theposition shown in Figsrc-5 of. the drawings; The lower clamping jawsare mounted upon slides? b, which have rack and pinion connections with-(the rod 72 and its operating handle 6,- so that when in the position described the clamping bar may be adjusted upor down to lace the necessary tension upon the warp t reads over'the separator shaft.

The drawing needle eis mounted upon the carriage E, which lattter. is adapted to slide lengthwise ,the machine and transversely the warp upon suitable ways formed in the bed The lead screw is continuously rotated during the operation of the machine for the gradual advance of the carriage by means of the gear f (Fig.2) carried at its end, said gear being driven through the intermediate gears f ff by the pinion ftiupon the end of the main drive shaft 9. :The intermediate gears 7, f are journa ed; on an armv f carried by the drive shaft: 9, which arm may be swung to any desired position and there clamped upon the clamping segment :ff permitting the substitution of gears of different sizes to change the ispeed of rota tion of the lead screw wheni desifed. The

drive shaft carries at its opposite end (F ig.

' 1) the loosely journaled driving pulley g,

which may" be clutched to the, shaft by means of the sliding clutch member g the latter in turn being operated by the lever 9 link. 9", upright lever g and horizontal sliding actuating rod gfl the latter extending 'the full length of the machine so that the main drive shaft clutch may be thrown in or out of engagement by the operator at any point along the machine.

The drive shaft is splined to permit driving engagement therewith of the gear 9 (Fig. 4) the latter mounted to SlldGlWltll the carriage lengthwise the machine and acting to drive the operating mechanismthereon. The gear 9 engages the needle operating gear 63, which latter acts through an intermediate gear and crank disk e to move the pivoted arm 6 and the link a for reciprocation of the drawing needle 6, which latter slides in a sleeve or cylinder e an'd is given a partial turn on its advance and retraction by the engagement of a pin upon the needle with a partially spiraled slot in the sleeve. The movement of the needle is so timed that it undergoes one complete reciprocation as the carriage is advanced a space corresponding approximately to the spacing between successive warp threads.

Acting in advance of the needle, and here in progressively advancing with thecarriage, there is provided thread-separating means for selecting and separating the foremost warp threads. In the described em is caused to advance lengthwise the shaft.

The advanced end ofthe sleeve is provided with a tapered end having corrugations (1 which as they pass beneath the warp threads tend to stroke the latter into parallelism and place increased tension thereon. Further advance thereof forces the threads upon the threaded portion d of the sleeve, where the foremost thread in engaged by the advancgng lip of the screw, successive threads bemg separated in accordance with the pitch Y of the screw and advanced one by one within the line of needle action. To maintain the threads 1n certain engagement with the separating. screw there is provided the overlying tension finger 03, carried by the swingin'g arm- (i supported upon the standard a)? and pressed against the threads engaged by the screw throughthe medium of the torsion spring d. Continuous and' suitable rotative movement is imparted to the separator shaft 03 and therethrough to the separating screw by the bevel gear (Z carried at the end of the shaft, and engaging the corresponding bevel pinion d upon the inclined shaft (Z the latter being driven from the bevel gear (it uponthe main driving shaft 9. a

The threads when engaged by the needle are drawn between suitably positioned lease members. 'llhese may be of any desired number and arranged for -any desired movement, but in the described machine they consist of a pair of lease rods 71., it (Fig. 4) and the separately movable lease rod 2'. ,The rods h, h on the one hand and the rod 2' on the other are held parallel With the travel of the needlebutcapable of vertical and opposite reciprocatory movement above and below the plane of needle action. purpose there are provided at opposite ends of the machine, vertically slidable in suitable guideways in the frame, pattern frames k supporting the rods it, It and pattern frames a" supporting the rod 2'. These frames are given reciprocatory movement through pins k and i secured respectively to the frames 71, and z" and engaging with suitably formed slots in the pattern disks/ a, he latter given a reciprocatory'.movement by the rocking shaft '10, which extends This shaft is os-" lengthwise the machine.

cillated by the crank arm 10 connected at I one end thereto, and its attached link 10 connected to the overhead crank disk /s*,'the latter being driven by agear leiinengage ment with 'thepinionk upon thesep'arator shaft d.

.lOL w For this Hy reason of the uniform and continuous reciprocatory movement which 15 given the pattern disk is, the lease rods are caused to reciprocate wertically between successive.

thread drawings, so that while positioned as shown in Fig. 3 prior to the drawing of one thread, they are subsequently reversed and ositioned as shown in Fig. 5 prior to the rawing of the next succeeding thread.

bers, such as the resilient bristles Z, 'or the like, the lower endsof which are held fast in the supporting bar Z, the latter however,

being so positioned as to present the line of bristles transverse to the line of needle action. This results in causing the free ends of the threads to be drawn and laid in the bristles, where they are heldwith suflicient certainty to prevent displacement of the leased Warp. The bristle-holding support- Z' is sustained by the depending hangers Z supported on the overhead frame a The free end of the thread after being withdrawn between the leaserods and through the bristles is stripped fromthe needle by thereciprocatory knock-off finger m, which on fullfretraction ofthe needle is caused to move transversely across "the needle path and strip the free thread end from the needle hook, returni however,

to its normal position beior et e nextadvance of the needle. The stripper pivoted upon the frame at and is givenre+ ciprocatory movement like that of a connecting rod through its connection to the crankdisk m the latter being driven. by the bevel gearing m from the carriage countersha'ft m the latterv in turn being driven from the needle operative crank disk e".

'The-proportions of' the gears are suchthat the stripper is caused to execute its strippin movement upon each retraction ofthe nee le. u

U pen-the drawing-of each thread between the lease rods' the last thread drawn is pressed backfagainst the remainderof the already leased warp to-thrust aside the leased threads away from the line of .needle action. This is accomplished by the forked displacing lever n (Figs; 3-5), the two bifurcations of which workbetween adjacent lease rods and are movedijrom one side of the line of needle action after the'needle retraction across the line of needleaction to worm o oflarge diameter.

displace the leased threads to one side. The

displacing lever is pivoted at or. upon the carriage E to travel therewith, and is also connected to the crank disk at by the link connection n The crank disk being rotated by the bevel gearing referred to, and the d stance 'be-I tween the center of the disk and its connection to the link a being less than the distance between the lever pivot n and itsconnection to the link, the displacing lever receives a suitable swinging reciprocatory movement from the rotation of'the disk.

The advance of the drawing needle is proportioned by suitable selecting gears f ft with close approximation to the spacing of the warp threads. The threads of a warp,

however, usually present localized irregularities which tend' to cause the foremostwarp thread to deviate more or less from the line of needle action. To suitably correct errors of this kind there is provided a hand adjustment accessible to the operator of the machine for adjusting the entire'se riesof warp threads lengthwise the travel of the needle and properly alining the foremost thread thereof with the axis of the needle. For this purpose the overhead end rod 9 is suitably journaled for rotative movement in the frame, a? and is provided at one end with the pulley 0, which is connected by the depending bandor belt of with the underneath pulley 0 the latter journaled in the machine and secured to the The latter is caused to engage with suitably formed teeth in the side or face of the adjacent hanger rod b upon the warp carriage, so that on movement of the worm the carriage is given a slight compensating movement lepgthwise' the machine.

For the purpose of operating the machine- With reference to a series of warps fof sl1ghtly varying width where it is undesirable or inconvenient repeatedly to change the gears f f with each new warp placed on the machine, or where variations in the warp widths may be too slight for compen sation through a change of gears, it is desir? able also to provide, either with, or in sub stitution for, the hand adjustment described, an automatic compensating feed-v which shall correct for. deviations in the average spacingof the warp threads from the assigned periodic advance of thedraw-v ing needle.'- With such automatic, compen= saiting feed the carriage driving/gears are proximately to the spacing of the warp threads and the warp carriage in addition is also given a slight incremental step-bystep advance to correct for deviations ofthe carriage advance from the exact amount which is desired. For this purpose near the end of the lead screw '7 (Fig, 2) there is a justed to give a feed corresponding ap-. I

provided a cam 72 which engages at each rotation of the lead screw with a swinging arm 72, one end of which is pivoted to the frame and the opposite end adjustably secured to a connecting rod or. link 39. The opposite end of thelatter is secured to a swinging pawl lever p (see Figs. 6 and 'i) fixedly secured to a pin 2 the pin carrying at its opposite end a pawl 32?. lihe pin, itself is journaled in an arm p", the latter swingingly mounted upon the end of the shaft which, carries the'worm.o but provided with some friction device, such as the spring pressed Washer 12* so that there is provided a slightresistance to its swinging movement upon the said shaft. When the rod or link is advanced by engagement ,of the lead 5 aft cam with the arm 32, the

pawl pin; is turned to carry the pawl against the serrated edge of the ratchet wheel 39 secured to the worm 0 to give the latter a slight rotative movement, the arm 39' being then held by the friction device referred to.

completed with the arm The moment the pawl nose engages with the ratchet wheel the movement of. the pawl is p and the lever I moving as a unit. When the leadshaft cam drops away from, the lever arm p, the latter is returned by the spring p moving the lever 12* against the stop screw p" upon the lever arm 10, and causing the return of the parts t'othe position shown'in Fig. 2. There Y is given therefore for each revolution of the lead screw shaft a slight shifting movement of the warp carrier, the movement of which can be varied by adjusting the stop screw 1)" or the connection between the rod and the swinging arm 70'; .Theamotin't and direction of this shifting movement may be pro-' portioned to maintain a correct alinement between the drawing needle and the foremost Warp thread, I

To assist the operator in moving the parts of the machine by hand for adjustment or other purpose, the lead screw end is provided with a crank handle r and the needle operating gear is also provided with a sep- .ara'te crank handle 1". -The operator customarily stands at the side of the machine near'the warp carriage and to enable him to *move the needleby hand from that side of i 'the machine, there is provided a pulley connected to the needle driving gear c throughthe main shaft m and gears m and m" at one" side and at the other side conmeted-through. the band or belt r -with the overhead pulley r which latter has the crank handle 1*? accessible to the operator on the opposite side of the machine.

3 While I have shown and described one form of my invention, it is to be understood that the same is not limited to the details herein shown, or the particular arrangement of operating parts, or the mode of sustaining the Warp with reference to the operating cent the same, means for progressively messes elements of the machine, but that extensive modifications in the illustrated details may be made and wide departures therefrom followed without deviating from the spirit of my invention.
